Greetings!

My BV11-46 started crackling and smoking and when I opened it up, this is what I found (one or both capacitors probably went bad). Is it better to repair these (and potentially other components) or replace the whole board? What are options (US or Europe/Poland preferrably)? Expected costs? If these went bad, anything else that should be replaced?

Also need a replacement glass...any suggestions?

 

Thanks!

Gene

Those are the standard mains suppression capacitors that have been fitted to most electronics since the 1970s. They can fail and, when they do there's usually a bang and some smoke, but I would have though this TV was far too young for that.

I wonder if this is tied in with a visit we had a year or two back to change out a board on our Beovision Eclipse TV as a "preventative maintenance precaution" due to a potential failure issue that had been identified? As I'm in the UK, our lovely new forum owners, Multicare, contacted us directly and came and did the job for free, but I wasn't home that day so didn't find out exactly what it was they changed.

As the TV is fairly recent, I would say that your best port of call initially would be a B&O dealer if you have one nearby.

Just replace those two paper foil capacitors. As said, it a common thing.
I've already done some, these were also boards from BV11's. But also some psu's from Essence mk2's and ML/NL converters.
After replacement the powersupplie will work again.

Quite a challenge to achieve "Less is More" while having the Beovirus.
